るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides an underwater oil storage tank, more specifically, a cylindrical body made of a flexible material in a tank provided underwater, and a liquid with a light specific gravity is placed inside the cylindrical body. , and relates to an improvement of an underwater oil storage tank in which a liquid with a heavy specific gravity is placed outside the tank.
従来、石油備蓄の一方式として水中にタンクを設ける所
謂水中備蓄方式がある。この水中備蓄方式にはタンクを
水中に係留する場合と着底させる場合とがあるが、倒れ
も油タンク外に取出したときその浮力と外圧を相殺する
ため、この取出した油の体積を海水等で置換する必要が
ある。ところで、との油水置換方式においては、比重差
利用、即ち、油の取出口をタンクの上部に設け、一方海
水の流出入口をタンク下部に設は両者の比重差により油
と海水を分離しようとする思想があるが、実際には、油
水の境界層では油がエマルジョン化したり、スラッジな
ど比重が潅水より重いものもあシ油水かどうしても混り
合ってしまう。BACKGROUND ART Conventionally, as a method of stockpiling oil, there is a so-called underwater stockpiling method in which a tank is installed underwater. This underwater stockpiling method involves either mooring the tank underwater or letting it land on the bottom, but in order to offset the buoyancy and external pressure when the oil is taken out of the oil tank, the volume of the taken out oil is stored in seawater, etc. You need to replace it with . By the way, in the oil-water replacement method, the oil and seawater are separated by utilizing the difference in specific gravity, that is, by providing the oil outlet at the top of the tank and the seawater outlet at the bottom of the tank. However, in reality, oil becomes an emulsion in the oil-water boundary layer, and substances such as sludge, which have a specific gravity heavier than irrigation water, inevitably mix with reeds, oil, and water.
このようなことから本発明者は、タンク内に可撓性物質
からなる筒状体を設け、該筒状体の内側に比重の軽い液
を、またその外側に比重の重い液を入れるようにして油
水分離を確実にし、かつ該筒状体をタンク上部から出し
入れ可能にして、該筒状体の保守９点検を容易にした水
中貯油タンクを先に提案した。For this reason, the inventor provided a cylindrical body made of a flexible material in the tank, and placed a liquid with a light specific gravity inside the cylindrical body, and a liquid with a heavy specific gravity outside the cylindrical body. We have previously proposed an underwater oil storage tank in which oil and water separation is ensured, and the cylindrical body can be taken in and out from the top of the tank, making maintenance and inspection of the cylindrical body easy.
ところで、かかる水中貯油タンクにおいては、貯蔵量が
多量となると大型化し、高さが数十メートルから百メー
トル以上にも達することとなる。したがって、可撓性物
質よりなる筒状体を交換または保守点検のためクレーン
船等により引上けようとする場合、潮流や風波等の影響
によりその作業は困難となる。加えてこの筒状体を船上
に引上げるためには高揚程のクレーンを必要とすること
となる。By the way, in such a submersible oil storage tank, when the amount of storage is large, the size becomes large, and the height reaches from several tens of meters to more than 100 meters. Therefore, when a cylindrical body made of a flexible material is to be lifted up by a crane ship or the like for replacement or maintenance inspection, the work becomes difficult due to the effects of tidal currents, wind and waves, etc. In addition, a high-lift crane is required to lift this cylindrical body onto the ship.
